SPECIFICATION forming part of Letter Application filed February z5,1895. senti No. 539,604. (No model.)

T all whom it may concern,.-

Beit known that I, JOHN NETREFA, of Cleveland, in the county of Cuyahogaand State of Ohio, have invented lcertain new and useful Improvements inSlicing and Paring Machines, of which the following is a specification,reference being had to the accompanying drawings.

The object of my invention is to produce a device adapted to facilitatethe operation of slicing or paring with economy and dispatch;

and it consists in the employment of certain novel mechanism hereinafterdescribed.

In the accompanying drawings, Figure I is a perspective view of mymachine. Fig. II is a central vertical sectional View of the same,

- showing some of the parts in elevation. Fig.

III is a top plan view of the cutting-disk. Fig. IV is a bottom planview thereof. Figs. V and VI are sectional views thereof on the lines 55 and 6 6 of Fig. IV. Figs. VII and VIII are top and bottom plan viewsof the disk-frame, and Fig. IX is a view of the feed-A` box and cover.

Referring to the iigures on the drawings, 1 indicates the frame of mymachine, constructed of any suitable material, preferably metal,consisting of a supporting-belt 2, supported by legs 3, secured at theirupper extremities, as by bolts 4, to lateral lugs 5, projecting from thebelt, and of horizontal brackets 6 upon the legs.

'7 indicates the body part or receptacle, preferably constructed ofsheet metal and of a downwardly-convergingcylindrical form, permittingof its being supported by the belt .2 and its easy detachment therefrom,it being apparent that the 'receptacle may be lifted from the frame bythe handles 8, provided for that purpose, when it is desired to clean orrepair it. The receptacle is preferably formed in two parts 9 and l0, asillustrated, which are provided, respectively, with heads 11 and12,-which, when the two parts of the receptacle are joined, willconstitutea cylindrical head 13 for the receptacle, the parts beingbolted or otherwise secured together when in use. .t

14: indicates a vertical shaft extending through the Vhead and suitablyjournaled therein, secured to which, above said head, is a beveled gear15, meshing with a somewhat larger gear 16, carried upon a horizontalshaft 17, journaled in the bearing-brackets 18, supported upon the head.

19 indicates a power-Wheel secured upon the opposite extremity of theshaft and adapted to impart rotation to the shaft 14 through theintermediate mechanism.

20 indicates a cuttiug-disk carried upon the shaft 14 immediately belowthe head and adapted to be revolved at a high rate of speed.

21 indicates an elongated and preferably Somewhatcurved feed-aperture inthe head 11, intowhich the vegetables or other articles to be sliced-areplaced resting upon the cutting-disk and designed to be sliced or paredthereby, a feed-box 2V2,of a shape correlative with that of the apertureand having an apertured top, being inserted into the feed-aperture toretain the vegetables against the disk,

the feed-box when desired.

24 indicates the chute projecting downwardly from the belt, adapted todirect the product of the machine into a suitable receptacle25,supported therebelow upon the brackets 6.

The device described constitutes the general construction of my machine,but isemployed merely as the necessary mechanical accompaniments of anovel cuttingfdisk, by the peculiar construction of which I am enabledto pare or slice any desired article by a clean graduatedcut, preventingall'bruising or tearing of the article and permitting ot' the cutting ofslices of various thicknesses by an adjustment of the device, which maybe accomplished without appreciable labor or loss of time.

26 indicates the frame of my disk, which vided with a lateral peripheralflange 28, and of a central disk 29, having secured above and below it,respectively,"a triangular block 30 and astrengthening-disk 31and'connected with the band 27 by spiral or hyperboloidal spokes 32,provided upon their outer edges with a flange 33, upwardly projecting toabout the height of the annular flange 28, against which is secured theback of a spiral or hyperboloidal knife 34, slightly upwardly inclined,as illustrated, and braced by a brace-flange 35.

36 indicates bridges spanning the space be` consists of a circular stripor band 27, prof a cover 23 closing the aperture in the topot' n speed.

tween the spokes and the band to strengthen the frame and render thesame rigid.

37 indicates a circular gage-plate fitting within the annular flange 28and provided with slits or elongated knife-apertures 38, permitting itto lie fiat against the band 27 and in a lower horizontal plane than theknives.

In order to regulate the thickness of the sl ice to be cut by the knivesof the disk, it is necessary that some means be provided for regulatingthe vertical distance between the gageplate and the cutting-edges of theknives. For this purpose I provide spring-thimbles 39, suitably locatedupon the frame project# ing therebelow and provided with apertured heads40, through which project gage-pins 41, secured to the gage-plate andscrew-threaded at their extremities to receive the thumbnuts 42.

43 indicates a spiral spring surround ing the pins within the thimblesand bearing against the heads 40 and th-e gage-plate, whereby the platewill be held yieldingly in as close proximity to the knife-edges as thethumb-nuts will allow. It is obvious that by screwing the thumb-nuts inone direction or the other the cut of the knives may be regulated byproperly adjustingthe gage-plate. The gage-plate is provided with anaperture 44 to receive the triangular block, the disks 29 and 3l andblock .30 being provided with correlativo apertures for the reception ofthe shaft i4.

The operation of my device is as follows:

Supposing it is desired to slice a number of vegetables, they are placedin the feed-box 22, and power being applied through the wheel l9,shaft17, gears 16 and l5, and shaft 14 the cutting-disk is revolved .at ahigh rate of The weight of the vegetables retaining the same upon thegageplate,the knives make a long sweeping cut, which by reason of theshape of the knives and their' corelation is practically continuous. Ido not desire to limit myself to the details of construction hereinshown and described, but reserve to myself the right t0 vary, modify,and change the same within the scope of my invention.

What I claim isv l. In a slicing and paring machine, the combinationwith a frame and actuating mechanism, of a rotatory unyielding cuttingdisk provided with a knife and a yielding gage plate, substantially asspecified.

2. In aslicing and paring machine, the combination with a frame andactuating mechanism, of a cutting disk, knives supported above thedisk', and an adjustable gage plate intermediate of said knives anddisk, substantially as specified.

3. The combination with a cutting disk and knife, of an intermediateadjustable gage plate, substantially as specified. f

4. The combination with a cutting disk and a knife supported thereabove,of a gage plate intermediate of the knife and disk, and meansfor'securing a yielding adj ustment of the gage plate, substantially asspecified.

5. The combination with a cutting disk and knife supported thereabo've,of a gage plate supported above the disk and provided with an aperturethrough which the knife projects, substantially as specified.

y6. The combination with a cutting disk and knife, of an intermediategage plate, and a spring between the disk and gage plate, substantiallyas specified.

7. A cutting disk consisting of a frame and plurality of knives, ofspring thimbles upon the frame, gage pins projecting from the gage plateinto and through the spring thimbles, spring surrounding the gage pinswithin'the springthinlbles and bearing against the gage plate and theend of the thimble, respectively, and thumb screws upon the gage pinsbelow the thimbles, substantially as specified.

8. A cutting disk consisting of a frame having a peripheral fiange andknife flange projecting at right angles to the frame, a knife secured tothe knife ange and conforming to its contour, and a gage plate fittingwithin the peripheral flange and provided with a slit through which theknife and knife flange project, and means for adjusting the gage plate,substantially as specified.

In testimony of all which I have hereunto subscribed my name.

JOHN NETREFA.
